CARPET-FASTEN ER.

SPECIFICATION forming part Of Letters Patent NO. 600,514, dated March15, I898. Application filed February 17, 1897. erial No. 623,807. (Nomodel.)

To ctZZ whom it may concern.-

Be it known that I, EDWARD A. COLL, a citizen of the United States,residing at Pitts burg, in the county of Allegheny and State ofPennsylvania, have invented a new and useful Improvement inCarpet-Fasteners, of which the following is a full, clear, and exactspecification.

My present invention relates to a new and useful improvement in devicesfor securing carpets to floors without the necessity of driving tackstheretliirough, and has for its object to improve upon the constructionshown and described in a certain application for Letters Patent filed byme upon the 16th day of September, 1896, and bearing Serial No. 505,965.

lVith these ends in view this invention con sists in the details ofconstruction and combination of elements hereinafter set forth, and thenspecifically designated by the claim.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, the constructionand operation will now be described in detail, referring to theaccompanying drawings, forming a part of this specification, in which-Figure 1 is a perspective of a nail made in accordance with myimprovement and an eyelet secured in the edge of a carpet for engagementwith said nail; and Fig. 2 is a section of a portion of a carpet and theeyelets secured therein, showing it in engagement with the head of thenail.

In carrying out my improvement as here shown I provide a nail A, thebody thereof being suitably sharpened, so as to be readily driven withinthe iloor, and this nail has secured thereon or formed therewith thehead B, which is of such shape as to readily enter into engagement withan eyelet C. By slotting the head, as indicated at D, a certain amountof resiliencyis given to the two halves thereof, so that when the eyeletis forced thereover these sections will spring toward each other andexert sufficient tension upon the sides of the eyelet to prevent itsaccidental withdrawal from the head, and as a further protection againstwithdrawal of the eyelet from the head the eyelet may be reduced ininternal diameter at the lower por tion thereof, as indicated at E, sothat when it is forced over the head the sections of the latter willfirst spring toward each other and after passing the reduced portion ofthe eyelet will react outward, as shown in Fig. 2, thus securing theeyelet with sufficient force to prevent its accidental disengagement.

In practice the slot D may be extended downward into the body of thenail and be utilized as a tool-seat and gage for driving the nail to theproper depth-as, for instance, when the nail is driven so as to bringthe bottom of the slot level with the floor this will be an indicationof the proper depth.

In applying the eyelet to the carpet, before the lower portion E thereofis turned outward to form the flange F, it is forced through an openingpreviously made in the carpet by a sharp-pointed tool, which crowds thethread thereof sidewise, but does not cut the same, after which theflange F is formed in any convenient manner, preferably so that theupper flange G, as well as the flange F, will be embedded within thefabric sufficiently to avoid coming in contact with the floor or theshoe of a person Walking thereon. This arrangement permits the carpet tolie flat upon the floor and avoids any rocking movement at the pointswhere the eyelets are secured and also any rocking movement of furnitureplaced thereon at these points.

One of the principal advantages of my improvement is that the cost ofmanufacture is exceedingly small, while at the same time the fastener isrendered very durable, since no delicate spring parts are formed in theeyelet, and itis, therefore, not easily disarranged.

Having thus fully described my invention, what I claim as new and usefulis-- In combination an eylet formed of a single piece of sheet metalbent into cylindrical form, flanges around the top and bottom of thecylinder for securing the eyelet in the carpet, a shoulder formed in thecylinder by abruptly reducing the diameter thereof, and a nail, aspherical head on the nail, said nail having a vertical slot run throughthe head into the body of the nail, said slot dividing the head into tworesilient halves to engage the shoulder of the eyelet, said slot beingadapted also for the reception of a tool the ends of which project oneach side of the nail and determine the depth to which said nail can bedriven, substantially as described.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses.

EDWARD A. COLL.
